No storage available for session. We will not send any data.

Describe the bug

When configuring the Microsoft Teams integration(TABS) with Datadog, the integration fails to send alerts to the designated Teams channel. Instead, the following error message is displayed:

"No storage available for session. We will not send any data."

This issue prevents Datadog from posting data (alerts, notifications, etc.) to the Teams channel, rendering the integration unusable for receiving Datadog alerts. The error implies that Datadog cannot properly store or manage the session data required to send notifications to Teams, possibly due to permissions, network restrictions, or integration misconfiguration.

Expected behavior
in normal browser it works perfectly fine but gives issue in msteams tab app.

Hi @VKZycus ,

Thank you for reaching out!

This might be due to the cookie support in MS Teams Tab environment. Here are some docs on session storage configuration. Could share your SDK version and init configuration so we can have a look?

[VKZycus]

window.DD_RUM.init({
clientToken: dataDogClientToken,
applicationId: dataDogApplicationId,
site: dataDogSite,
service: dataDogService,
env: dataDogEnv,
version: '1.0.0',
sessionSampleRate: 100,
sessionReplaySampleRate: 0,
trackResources: true,
trackLongTasks: true,
trackUserInteractions: true,
enablePrivacyForActionName: false,
allowedTracingUrls: [(url) => true]
});

Hi @VKZycus ,

Could you try to add sessionPersistence: "local-storage" in the init and see if it works?

Hi @cy-moi , It worked. Thanks a lot.
Reason - Msteams restrict cookie of third party apps.storing in local storage works.
